The "John Patten of Marblehead and his family" is, I believe, the John that I already know about. It's his father (and family) that I can't seem to find, except for some educated guesses. It's possible he immigrated (landed) at Salem, Boston, or even at Marblehead in a fleet of five ships (as yet unidentified passenter lists) which supposedly arived in 1718.
I've been away from this for a year or more. It's not exactly a high priority for me now, but thanks for the offer.
If I ever get back on the Pattin/Patten line, I'll be looking here again.
